[OASIS Issues Tracker <workgroup_mailer@lists.oasis-open.org>]

     [ http://tools.oasis-open.org/issues/browse/ODATA-144?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Michael Pizzo updated ODATA-144:
--------------------------------

    Proposal: No longer relevant for $select, based on ODATA-32. We will adopt grouping of properties for $aggregate as the only way to specify multiple or aliased sub properties of a navigation.  (was: Allow 
    $select=Items/(Price,Currency,Quantity,Unit) 
as a shortcut for 
    $select=Items/Price,Items/Currency,Items/Quantity,Items/Unit
)

No longer relevant for $select, based on ODATA-32. We will adopt grouping of properties for $aggregate as the only way to specify multiple or aliased sub properties of a navigation.

The parens are required only if you have more than one property or in the case that you use an as.

legal:
$aggregate=Items/Price 
$aggregate=Items/(Price) 
$aggregate=Items/(Price as AggregatePrice) 
$aggregate=Items/(Price,Amount) 

not legal:
$aggregate=Items/Price as AggregatePrice 
$aggregate=Items/Price,Items/Amount

>
> The current syntax for $select requires to qualify each single included property with its navigation path. We propose an alternative/additional syntax that allows grouping by path:
>     $select=Items/(Price,Currency,Quantity,Unit) 
> The same notation would be useful for the data aggregation extension:
>     $aggregate=Sales/(sum(Amount),average(Amount) as AvgAmt)
